How to Choose a Folding Treadmill
Deck size
Walkers can use 50 to 55 in. decks; runners want 60 in. long and 20 in. wide or more.
Motor and speed
2.5 to 3.5 HP handles most home use. Check top speed if you run fast.
Incline
Auto incline (10 to 15%) adds calorie burn without running faster.
Folding style
Hydraulic soft-drop decks are easiest. Walking pads fold flat and slide under furniture.
Capacity and weight
Choose a max user weight at least 50 lb above yours; heavier frames feel more stable.
